Cell Membrane controls the exchange of substances between the cell and its surroundings Nucleus contains the cell's genetic material and controls cellular activities including division Chloroplast location of photosynthesis to produce food molecules Ribosomes location of protein synthesis in the cell

evolution the process of change that has transformed life on earth from its earliest beginnings to the diversity of organisms living today biology the scientific study of life examples of properties and processes we associate with life order, evolutionary adaptation, response to the environment, reproduction, energy processing, regulation, growth and development emergent properties new properties that arise with each step upward in the hierarchy of life, owing to the arrangement and inter...

Evolution - Development of life on earth - Theory of evolution by natural selection - conflicts with theory of special creation - Theory of Special Creation -proposed that species are independent and unrelated -life on earth is only 6000 years old and species do not change because life is created by supernatural being 2 types of Evolutionary Thoughts Pattern component: it summarizes the facts observed in natural world Process component: proposes a mechanism explaining the observed patt...

Thomas Malthus is best known for his idea that more offspring are produced in any generation than can possibly survive A theory, to a scientist is an overarching body of knowledge, consisting of facts, observations, and tested hypotheses The HMS Beagle spent most of its five year voyage mapping the coast of S. America The Origin of Species was published in what year? 1859 The "watchmaker analogy" is most closely associated with William Paley The scientist who first proved that extinctio...

systematics an analytical approach to understanding the diversity and evolutionary relationships of an organism, both present day and extinct biodiversity variety of organisms and the ecosystems they form taxonomy ordered division of organisms into categories based on a set of characteristics used to assess similarities and differences classification grouping organisms by their similarites or relationships phylogeny 1. evolutionary history of a group of organisms from a common ancestor; 2....

What is the stinging organelle that assists it in capturing large prey? Trichocyst Which species of amoeba did you observe under the microscope? Amoeba proteus Which experimental group receives the treatment? Control group A solution that tends to release protons is An acid The portion of a phospholipid that contains the phosphate group has one or more electrical charges. That makes this region of the molecule Hydrophilic The Biuret test is used to detect the presence of which group of mac...

Darwin’s theory of evolution is a strong theory, but at the time of proposing the theory, some aspects were yet to be explained. Which of the following things below did Darwin understand and incorporate into his theory? a. That inherited variations could increase an organism's ability to survive and reproduce b. How chromosomes were inherited c. That genetic mutation could be responsible for making new alleles d. That genes were the templates for making proteins a. That inherited varia...

Identify the different types of point (base substitution) mutations; missense, nonsense and silent mutations. POINT MUTATION: = A change in a single nucleotide Types: 1) Silent Mutation = When the redundancy of the genetic code kicks in and the change in that single nucleotide results in the same amino acid produced as the original code. 2) Missence Mutation = When the change in a single amino acid changes the amino acid produced 3) Nonsense Mutation = When the change in a single nucl...

The smallest unit that has all of the characteristics of life is the Cell Nutrient molecules are used to build cellular structures or for energy. This best represents which characteristic of life? Living things acquire materials and energy from the environment. Organs are composed of tissues, which are composed of cells. This is an example of which characteristic of life? Living things have levels of hierarchical organization. The blueprints for structural organization and metabolism are co...

Digestion process of transforming food into basic nutrients that can be absorbed and used by the body Without the process, the nutrients we initially consume in food would be useless: digestion Before food even enters the mouth, a cascade of events involving the nervous system and a variety of hormones are set off based on a variety of stimulus: cognition, sound, odor, appearance, and taste cognition thoughts about food can start the flow of saliva sound hearing a description of the meal ...
